Most of the time when you argue with someone, you realize that the reason you can't persuade them is because they're not really listening. They remain detached for fear of being infected by your ideas, amirite?

I forgave this lexical error, haha. because I feel the sentiment of this post.

While I don't agree with "most", I've experienced this a lot too, when it's clear people haven't listened to a word you've said. Perhaps the thing about being infected is a bit much too, but the general idea of people just ignoring what you say completely and not taking anything on board is quite right.
